Soyo K7V Dragon Plus! related problem

If you remove the CPU the unit will not post to BIOS. That will get
you nowhere. If the heatsink were not seated properly on the CPU the
unit would begin post and shut down from overheat within a few
seconds, so I don't think that is your problem. If your vid.card were
bad, you would (should) get a series of code beeps from the system
beeper indicating a problem with it, and you aren't getting that so I
don't think its your vid.card. If you have an extra card lying around
swap it even if it is old just to test.

If you are not getting a post beep, the CPU isn't even reaching the
BIOS (which is hardwired into the mobo). So we have to go farther
back.

First, make double sure that your power cord from the Power Supply is
securely and properly plugged into the mainboard, although I don't
think this is the problem. Next, remove the CMOS battery and let it
sit for 15 minutes. If this board has a BIOS reset jumper use that to
set the BIOS back to default settings. It is usually located close to
the battery-check your manual. Reinstall the battery and try to boot.
I have had the experience of the CMOS settings getting corrupted and
preventing post.

If no joy, I suggest getting a power supply tester and make sure that
one of the rails is not faulty. You can get them from Newegg.com
(Powmax) for about $8 +shipping.

If still no joy, you will have to swap out the CPU with one you know
is good. Yeah, I know this is a pain, but....

One last thing to check is that there are no shorts from the mounting
of the board on the metal case underneath. I am not sure if you took
the mainboard out of the case or not, but thought I would mention it.

If STILL no joy, your board is dead. I suggest the Shuttle AN35N Ultra
from Newegg.

My K7V D+ suddenly got the same symptoms the other day. It crashed and
after that became increasingly unstable as I tried to diagnose the
problem until it behaved like you describe.

Try remove the RAM. Then my board beeps like it's supposed to.
I've checked the RAM in another machine and it seems ok. I've replaced
the video-card and it doesn't seem to affect anything. I've removed all
drives. It seems the MB is bad. Maybe yours is too. A shame... it's a
nice MB.

Something isn't being told here. Since when did a move require a complete
break down of a machine? If you just disconnected the monitor, keyboard and
mouse for a move to a new location I would look at the possibility that
something got jiggled loose. Check that all components are properly seated.

Now if its like it sounds and you completely took the thing apart and put it
back together I would look to see if you didn't crack the cpu core while
re-installing the cpu fan.

Or maybe just capacitors are going bad...that's easy to replace if you have
some skills<!-- ~MESSAGE_AFTER~ -->

Hmm... which skills. Ordering parts and soldering are no problem, but I
don't know the nature of this board. Soldering a multilayer PCB without
knowledge of its design is new to me.

True. I didn't have to do it (yet!)...but i guess if the problem are leaking
caps, it shouldn't be too difficult. In fact, you have nothing to loose:
The board now doesn't work, so if replacing caps goes wrong, it still won't
work, which means that basically you can't break anything, you just have the
chance to repair <!-- ~MESSAGE_AFTER~ -->

Nahh... There's plenty of other reasons for it to behave strange. I
changed the PSU to a quality Enermax and now it runs fine. I changed it
back again to the normal Macron MPT-400 and it still runs fine. Weird....
Sometimes computers are like plants... talk to them and nurse them a
little and they get better

Soyo motherboards are notoriously finicky, simply installing the
cards in a different order could cause this. Unplug, and reset the CMOS
for starters, with maybe just the video, one stick of ram, keyboard.
Even if it doesnt post, try again later - my Soyo Dragon Ultra Platinum
used to do all kinds of strange things, but I was overclocking. It
always came back to life for me. But my Dragon plus I leave alone, its
running fine as is, and I really dont want to screw up my sons computer

True...i think maybe replacing the caps would be last solution before you
ditch it...<!-- ~MESSAGE_AFTER~ -->
